5.15 _9111_AD_Set_Channel
@ Description
This function is used to set AD channel by means of writing data to the
multiplexer scan channel register. There are 16 single-ended A/D
channels in PCI-9111, therefore the channel number could be set
between 0 to 15. Under non-auto scan mode, the ADChannelNo stores
the channel number setting. Under auto-scan mode, the ADChannelNo
records the ending channel number.
